The results on ERDs.

<p>The figure shows the mean and confidence intervals (<i>p</i> = 0.025, Bonferroni-corrected for multiple comparisons) of the ERDs in all the stimulation-band combinations where significant effects were found. All time points (before, during and after stimulation) and stimulation conditions (real or sham stimulation) are represented. An asterisk (*) marks the statistically different distributions (p<0.025, Bonferroni-corrected), according to post-hoc tests.
